Features/Changes:

- Wild Pokemon: All of the 251 Pokemon available will be catchable somewhere in Johto or Kanto. This includes those not originally included in Crystal such as Mankey, Mareep, Vulpix etc. Also, every area has had a level increase to fit the location in-game.
- Difficulty: The whole game difficulty has been increased.
- Gyms & Elite Four: All of the Gym Leaders and Elite Four Members have had a complete team overhaul.
- Trainers: All trainers around Kanto & Johto have been edited to fit their area in the game.
- Pokemon Stats: 40+ Pokemon have had an increase in their total stats.
- Moves: Some moves have had an increase in power and/or PP i.e. Giga Drain, Slash, Steel Wing etc.
- Evolution: All the evolution lines that previously required trade have been edited; you now only need to train to a certain level or use a specific item.
- Trades: Some of the in-game trades have been altered so that you now receive Pokémon that are harder to catch.

CGPaladin 11-22-12 - 11:26 AMThis game is so far pretty ok. So far a lot like crystal but more difficult. So far the only thing ive noticed is the starters are on the Johto map, and you can trade geodude for staryu. anything else im missing?

snorlaxrules 11-20-12 - 02:21 PMit says in the bio trade only pokemon will lvl up with items or by leveling
